Apologies for the scan quality.Pepe Rezende said:As a CFS2 developer, I need a good three view image of CAO.700 and Bloch MB.162 bombers. Can anyone help me?
The Kolko ACA-5 was mentioned and illustrated in AVIATION MAGAZINE No.727, 1978.
On the 9th June 1939 the technical director of SNCAO , former Loire-Nieuport, M.Kerguistel received a letter from engineer A.Kolko. Recommended by M.Caquot, president of the SNCA firm A.Kolko proposed his plans for a complete new aircraft concept.(patent Kolko Nr.825.657) Following this patent a tourist aircraft, a bomber to B.5 and a fighter was suggested all with a very compact look.
The main principle was to keep the concept compact by placing all elements of the construction as close to the center of gravitity as posibe , wile still retaining a great movability. Interested by this concept , M.Caquot ordered on the 13th of June a windtunnel model to be tested in the windtunnel of SNCAO.
Already on the 20th of June M.Kerguistel was ready with his first report about the results of the initial windtunel tests. Despite the longitudal stability was reasonable the stability on the ground should be far less. Several modifications to the fins and rudders could only partially solve the problem. Most of the calculated performances were found correct but the air intakes for the radiator and the cooling of the engine was very doubthfull.
In general it was concluded that the design had certain technical advantages, but has a lot of problems too.. By letter of the 22th June 1937 from M.Caquot all work at SNCAO was stopped. Maybe longer studies and tests could have resulted in a war winning fighter...

The CAO 810 was a dive bomber project powered by Hispano Suiza 12Y type 89 supercharged(1200cv at 6000m), remplaced by 12Z turbo supercharged(1300cv at 8000m).Jemiba said:As the exhaust stubs are visible, it obviously was piston engine powered.
Interesting find !
and finally the SNCAO CAO-810 dive bomber project,it was three seat low-mid wing,
powered by single engine,may be turboprop with twin tail fin,here is from two pictures,
from ebay on a site and a sketch to it from anther site;
